CONNECTION OB BINDING TERMINAL.

Application filed April 6, 1921. Serial No. 459,197.

To all whom z't may concern:

Be it known that I, RUDoLF ZiiLLNnn, a citizen of the German Republic,and residing at Dresden, Germany, have invented certain new and usefulmprovements in Connection or Binding Terminals, of which the followingis a specification.

' This invention relates to an improved connection or binding terminalfor electric conductors, which has essential advantages: 1. It ensuresan absolute safe and permanent contact of the conductors to beconnected; 2. The conductors can be easily and quickly attached thereto,whereby time is saved; 3. Any screws and thus damage by the same to theconductors to be connected or bound are omitted; 4. It is absolutelreliable, even when used in connection wit vibrating conductors, anyfaults in the connection of the conductors causing a heating of thelatter or a flickeringl of the light being thereby dispensed wit n theaccom anying drawing:

Fig. 1 is a p an view of a distributionblock (with removed cover)containing a plurality of the improved terminals;

Fig. 2 is a perspective view of such a distribution-block with cover.

Figs. 3 and 4 are partially sectional side views, showing the improvedterminal in its position of use, and in its position for an insertion ofthe electric conduit, respectively;

Figs. 5 and 6 show two details of the improved terminal in perspectiveviews;

Fi 7 shows a slight modification of one detai of the improved terminalin a perspective view.

The distribution-block comprises a porcelain base at having holes I; fora passage of the electric conductors therethrough and a plurality ofterminals attached thereto, the same being covered as shown at c,

The improved terminal comprises a cotter-pin shaped support 01 havingoutwardly extending feet e connected with one another, side members ofwhich the upper parts are spaced apart while the lower parts lie closelyupon one another, and a split head p with overlapping ends; a coilspringg; a washer it having two notches i therein forming a tongue k betweenthem; and a cap Z with downwardly extending rim m and having two similarnotches n therein forming a tongue 0 between them.

Said support (I is inserted in said porcelain base a from below througha hole therein, that is widened at its lower part for the reception ofthe feet 6, which thus bear against the ste formed by said lowerwidening, the ho e being then filled-out with cement f whereby thesupport 03 is firmly fixed in position.

Thereupon, the coil-spring g is mounted over said support d, the lowerend of said coil-spring bearing then upon the top of the porcelain basea, which is preferably recessed for a safe reception of the same, Thewasher h is then so placed upon the upper end of said coil-spring 9 thatit engages with its notches 71 over the spaced-apart upper parts of theside members of said support (1, its tongue is engaging then in thespace between said side members. Finally, the cap I is placed over saidwasher in such a way that its notches engage also over the side membersof the support (1 and its tongue 0 in the space between said sidemembers, but from the opposite side thereof, so that the side membersare embraced from both sides.

With empty terminal, the cap Z is allowed to move, by action of saidcoil-spring, in upward direction until its tongue 0 strikes against theunderside of the closed head 1 of the support all.

Fo intended use of the terminal, the cap Z with the washer h aredepressed against the action of the coil-spring g until they engage withtheir notches over the lower parts of the side members of the support d,which are thereby pressed apart, so that the split head 10 is opened(Fig. 4) for an insertion of the conductors to be connected or to bebound.

The overlapping ends of the slit head p may be situated either at thetop end thereof (Figs. 3-4) or laterally in proximity to the latter(Fig. 7), both constructions allowing a convenient insertion of theconduits.

Upon the cap Z being then released, it is again pressed upwards againstthe underside of said conductors ig. 3) by action of the coil-spring g,whereupon the binding (as shown in Fig. 3) or the connection of theconductors is completed.

What I claim, is:

A connection or bindin terminal comprising a cotter pin-shape supporthaving side members of which the upper parts are spaced apart while thelower parts lie close 1137 upon one another, a split head withoverlapping ends, and outwardly extending feet connected with oneanother; a coil-sprin located ove said support; a Washer place upon theupper end of said coil-spring and having two notches forming s tongue between them, and a cap placed over said washer and having two similarnotches "forming a tongue between them, said washer and cap embracingthe upper parts of the side members of said support from opposite sidesand adapted nesaeae the purpose set forth.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing 2Q witnesses,

RUDOLF ZGLLNER. Witnesses:
